rapply2d: Recursively Apply a Function to a List of Data Objects

Description

rapply2d is a recursive version of lapply with two key differences to rapply: (1) Data frames are considered as final objects, not as (sub-)lists, and (2) the result is never simplified / unlisted.

Usage

rapply2d(l, FUN, ...)

Arguments

l

a list.

FUN

a function that can be applied to all elements in l.

...

additional elements passed to FUN.

Value

A list of the same structure as l, where FUN was applied to all elements.
